Our curriculum, as I've mentioned before, evolves. Below are videos of releases using the older (for our school) kenpo-based moves and our current approach which is reference-point based.
Kenpo Based Defense from Rear Neck Grab
The reference point system is designed to respond to each attack by engaging and disabling your attacker, not just repelling him to attack you again. Also, the idea of reference points is to respond to each attack by funneling the response into a few well-known fighting maneuvers. The Lavallees self-defense, while similar to jitsu, is most directly derived from Israel-base haganah self defense. It avoids the kenpo self defense problem of there being many dramatically different moves for self defense. A cool-headed well-trained person might remember which defense to use in which situation but most people, once attacked, could get confused by the complexity of responses of the kenpo self defense.
(note - this videos were pulled together from an impromptu practice session after class. They are not performances)
I'd be very interested in your thoughts on which of these is more effective in what situations. And what you know about the heritage of these approaches...
